Wrong ordering by outline number

[dbarashev]

1. Create 10 top-level tasks and 2 subtasks under task 1
2. Make the outline number column visible and sort tasks by the outline number

The tasks will be ordered lexicographically, as if outline numbers were just strings.

Expected task order:

1
1.1
1.2
2
.
.
9
10

Actual order:

1
1.1
1.2
10
2
.
.
9

May I suggest this update to the bug report:

Insert WBS 1.1.1 and 1.1.2 between the 1.1 and the 1.2? This ensures developers recognize at least three levels of "nesting" in the WBS structure.

Expected task order:

1
1.1
1.1.1
1.1.2
1.2
1.3
2
2.1
2.1.1
2.1.2
3
.
.
.
9
9.1
10

WBS structures typically extend down three levels.
